Here is the equation:
⇒
You need to get "x" by itself so minus 3 from each side
⇒
⇒
Divide 8 by 2
÷
x=4
So each 4 is equivalent to 4
Lets check:
⇒
⇒
So that means that Marcus practiced the piano for 4 hours and Donnel practiced for 7
Step-by-step explanation:
1Ans: 4x = -36
× = -36/4
× = -9
2Ans: 5x -15 = 50
5x = 50 + 15
5x = 65
x = 65/5
x = 13
3Ans: 4(x + 2) -17 = 35
4x +8 -17 = 35
4x -9 = 35
4x = 35 +9
4x = 44
x = 44/4
x = 11
4Ans: 6x +12 = 4x -18
6x -4x = -18 -12
+2x = -30
x = -30/+2
x = -15
5Ans: 1/2 (4x -10) +5 = x -11
0.5 (4x -10) +5 = x -11
2x -5 +5 = x -11
2x = x -11
2x - x = -11
1x = -11
x = -11/1
x = -11
You divide 4÷3 and u were get your answer :v, sorry I'm lazy to answer it. but I'll give u the work
